Justification:
Listed as Vulnerable given its extent of occurrence is less than 20,000 km2, its specific habitat, "foggy desert", is under serious threat from tourism development, and populations are likely fragmented in several parts of its range.

There is no known information on population or abundance. This species is not considered to be common. Within its range, however, it is more common on the Gulf side of the peninsula than on the Pacific side (Alvarez-Castaneda pers. comm.).
